According to the American-European classification system (as modified by Tzioufas and Voulgarelis [5] ), diagnosis of primary Sjögren syndrome requires at least four of the criteria listed below; in addition, either criterion number 5 or criterion number 6 must be included. Sjögren syndrome can be diagnosed in patients who have no sicca symptoms if three of the four objective criteria are fulfilled. The criteria are as follows:

  1. Ocular symptoms - Dry eyes for more than 3 months, foreign-body sensation, use of tear substitutes more than 3 times daily

  2. Oral symptoms - Feeling of dry mouth, recurrently swollen salivary glands, frequent use of liquids to aid swallowing

  3. Ocular signs - Schirmer test performed without anesthesia (< 5 mm in 5 min), positive vital dye staining results

  4. Oral signs - Abnormal salivary scintigraphy findings, abnormal parotid sialography findings, abnormal sialometry findings (unstimulated salivary flow < 1.5 mL in 15 min)

  5. Positive minor salivary gland biopsy findings

  6. Positive anti–SSA or anti–SSB antibody results
